24 Claims.

The invention relates to a machine for making brushes of the typewherein the brush bristles or fibers are held between two wires whichare twisted to grip and retain. them. A machine embodying the presentinvention is in some respects similar to that shown in Patent No.2,358,443, issued September 19, 1944, in the names of Henry Cave et al.

The machine shown in the said patent is a fully automatic machine whichis entirely suitable for brushes of certain types. For brushes of othertypes, particularly when high grade, expensive fibers are used, asemi-automatic machine is preferable so that the operator may haveopportunity to visually inspect the fibers of each brush prior to thetwisting of the wires to make sure that the fibers are properlydistributed, and to manually change the distribution of the bristleswhen this may appear to be necessary. After inspection of the fibers bythe operator and after any necessary adjustment of the distributionthereof, the. twisting mechanism of the machine can be. started, inoperation by the operator to effect the twisting of the wires to holdand grip the fibers.

One of the objects of the. invention is to provide a machine of thegeneral character referred to having a magazine for brush fibers andhaving a carrier, which. is adapted to be positioned adjacent themagazine to receive fibers therefrom and which then moves in a generallyhorizontal direction to= a. twisting position within convenient reach ofthe operator so that the necessary inspection and distribution of thefibers can be taken care of prior to twisting.

A further object of the invention is to provide a. machine having acarrier which reciprocates horizontally between a fiber receivingposition adjacent the. magazine and a forward twisting position, thesaid twisting. position being as before stated, within convenient reachof the operator.

Afurther object of the invention is to provide, in association with thehorizontally movable carrier,. an automatically operated wire feedingmeans which serves to feed one wire to the car rier prior tothedistribution of brush fibers thereon. and which serves to feed asecond wire to. the carrier after the distribution of brush fibersthereon.

A still; further object of the invention is to provide, a machine of thegeneral character already set forth. wherein the. carrier not only moveshorizontally as stated, but also moves vertically, thus enabling a moresatisfactory spaced relas 2. tionship between the fiber magazine and thetwisting position.

A still further object of the invention is to provide a machine of thegeneral character described wherein the carrier, after reaching thetwisting position and after the wires thereon have been gripped by thetwisting mechanism, can be moved vertically downward to provide amplespace for the twisting operation without any interference with suchoperation by the carrier.

A. still further object of the invention is toprovide a machine havingthe general characteristics already set forth wherein the twistingmechanism is bodily movable horizontally with the carrier, but whereinthe carrier may be movable vertically independently of the twistingmechamsm.

Various other objects of. the invention will be apparent from thedrawings and from the following specification and claims.

In the drawings I have shown in detail a preferred embodiment of. theinvention, but it will be. understood that various changes may be madefrom the construction shown, and that the drawings are not to beconstrued as defining or limiting the scope of the invention, the claimsforming a part of this specification being relied upon for that purpose.

General description Referring particularly to Figs. 1 to 6 of thedrawings, it will be seen that the machine is provided with a carrierII] which is horizontally movable with respect to a main bed or base I2.This carrier has a generally horizontal portion and is adapted toreceive and carry two horizontal wires with a horizontal layer of brushfibers between the wires and extending transversely thereof. Suitablymounted in fixed relation to the base I2 is a magazine for brush fibersgenerally indicated at l4, and there is preferably also provided a wirefeeding means generally indicated at 16. The carrier II] can occupy aforward twisting position as shown in Fig. 1 in which position it isparallel with the magazine and in which position the wires can betwisted by a suitable twisting mechanism, a part of which is shown atl8, and it can also occupy a rearward position immediately adjacent themagazine M, as shown in Fig. 3, in which position it can receive a layerof fibers from the magazine l4. Preferably, provision is made forreciprocable movements of the carrier between these two positions, thecarrier being moved translationally and in parallelism, each positionthereof during movement being parallel with each other position; Thecarrier is shown as mounted on a slide 20 horizontally movable along aguideway 21 formed on the base l2. When a wire feeding means such as [8is provided, this means serves to deposit one wire A on the carrier inthe position shown in Fig. 2 as the carrier moves from r its twistingposition shown in Fig. 1 to its fiber receiving position shown in Fig.3.

With the carrier in the position shown in Fig. 3 a layer B of brushfibers is distributed on the carrier in a manner to be described indetail, and then the carrier is returned to the twisting position asshown in Fig. 5. In moving from the position shown in Fig. 3 to theposition shown in Y Fig. 5 the carrier passes through the intermediateposition shown in Fig. 4 and in this position the wire feeding means l6serves to deposit a second wire C on the carrier, the carrier thencarrying the two wires A and C with a layer B of brush fibers betweenthem. When the position shown in Fig. 5 is reached the layer of fiberson the carrier between the two wires can be inspected by the operatorand any necessary redistribution of the fibers can be made. It isfrequently desirable to remove a few fibers from each end of the layer Bto insure more satisfactory twisting. After the fibers havebeeninspected and redistributed, the wires A and C are then gripped in theusual manner by the aforesaid twisting means located at the twistingposition. The

twisting means serves to twist the two wires in 4 accordance withstandard practice to form a twisted brush. In order that twisting may beeffected by the twisting means without interference by the carrier, thecarrier is moved downward prior to twisting to the position shown inFig. 6.

Preferably but not necessarily, the fiber magazine I4 is in a relativelyelevated position and the carrier in moving from the position shown inFig. 1 to the position shown in Fig. 3 moves not only horizontally, butalso vertically upward. In returning from the position shown in Fig. 3to the position shown in Fig. 5, the carrier moves vertically downward.

A portion l8 of the twisting mechanism is shown in the twisting positionby dotted lines in Figs. 2, 3 and 4, but the said twisting means is notnecessarily permanently located in the said position. While theinvention is not necessarily so limited, the slide '20 which supportsthe carrier It may also support the twisting mechanism. Thus thetwisting mechanism is movable bodily with the carrier, the carrier andthe twisting mechanism remaining in fixed relationship to each other,except that the carrier is or may be movable vertically as alreadystated.

'The details of the carrier, of the fiber magazine, of the wire feedingmeans, and of various associated parts, together with the manner ofoperation, will now be described.

Carrier and operating mechanism therefor In describing the carrier andthe operating mechanism therefor reference will be had more particularlyto Figs. '7, 8,11, 14 and 18.

For supporting the carrier I0 there is provided a bracket 22 which isrigidly mounted on the slide 28. A slide 24 is provided which is.vertically movable in suitable guideways in the bracket 22, being heldin place by gibs 26, 26. The slide 24 has an integral rearward extension28 and the carrier IE9 has a cylindrical bottom portion which isdirectly supported in an opening in the upper end portion of theextension 28. The carrier has an integral lug 29 thereon which engages anotch in the slide 24 to prevent the carrier from turning. As shown moreclearly in Fig. 11, the slide 24 and the extension 28 thereof extenddownward through an aperture in the main slide 20.

As shown in Figs. 7, l4 and 18, the carrier H! has a generallyhorizontal upper portion which extends transversely beyond its support28 and beyond the bracket 22. The length of the carrier is at leastequal to the maximum length of the layer of fibers required for themaking of a brush. In order to insure that fibers deposited on thecarrier will lie transversely thereof, the carrier is provided at itstop with a plurality of upward extending transverse teeth 30, theseteeth being closely spaced throughout the entire length of the carrier.In order that the carrier l9 may more readily hold the wires A and Cdeposited thereon by the wire feeding means IE, it is provided withgrooves at its ends as indicated at 3| in Figs. 8 and 14.

In order that fibers deposited on the brush may be firmly held in placeduring movement of the carrier, the carrier is preferably hollow and theinterior thereof is connected with a vertical hole 32 extending throughthe slide extension 28. By mean of a flexible hose 34 the hole 32 in thesupport is connected with a suitable suction device so that a partialvacuum is maintained within the interior-of the carrier.

A suitablemeans is provided for reciprocating theslide 20: between thepositions shown in Figs. 8 and 11. These positions are also shown inFigs..-1, 3, and 6. The saidjmeans maybe widely varied, but as shown,there is a pneumatic cylinder 36 secured to the base t2, this cylinderhaving a piston therein carried by a piston rod 38- which extendsforward and is connected with a depending bracket 40 extending downward.from the slide 20. By means. of. piping 42 and 44 air'can be. admittedto the cylinder 36 in front of or behind the piston therein so as tomove the slide 20 toward. the rear or toward the front, as may berequired. Air under pressure is supplied through a pipe46 to a valveunit 48-. which is connected' with the piping 42 and 44. Thevalve unitmaybe operated by any suitable means but as shown there is a handle 58for this purpose. By manipulating th handle 50 the operator can cause.the slide 20, together with the parts carried thereby, to be moved tothe rearward position or to the forward position as; required.

As already stated, the fiber magazine 14 is preferably located in arelatively elevated position, and when the magazine is so. located,- itis necessary for the carrier I-U- to move not only horizontally but.also vertically. In order to efiect vertical movement of the carrier thesupporting slide 24- isprovided near its bottom with a transverseextension 52 (Fig. '7), and. this extension carries a roller. 54 whichextends into a cam groove 56 in, a. bracket 58 secured to the base of.the. machine, The shape of the cam groove 56 is such that. as the slide20 moves rearward, the slide 24 thereon is moved upward, the amount ofupward movement being so determined as to bring the carrier H1 intoproper cooperative relationship with the fiber magazine I when the.slide Ml is in its rear position. When the slide 2,0 moves forward thecam groove 56. causes the carrier ID to move downward so that when theslide reaches its forward position the carrier is in register with thetwisting. position of the twistingv mechanism.

As already stated, it is necessary for the carrier ID to be moveddownward after the wires A and. C have been engaged by the twistingmechanism preparatory to twisting. The .forward. end of the cam groove56 is provided with a downward extension 60 (Figs. 8 and 11) whichpermits the roller 54 to move downward. When the slide. 20. reaches. itsforward position, the slide 24 which supports the carrier I ii isnormally supported by a vertically movable plunger 62 mounted in abracket 64 on. the bracket .58. The plunger 62 is resiliently held inits uppermost po sition by means, of a coil spring 66. The plunger 62.engages the bottom of the extension 52 to thus support the. slide 2 andthe. parts carried thereby. For moving the slide 24 and the partscarried thereby downward, the bracket 58' carries a vertically slidablerod '68 which is engageable at its lower end with the top of theextension 52. The upper end of the rod '68 is pivotally connected with alever which is pivotally connected with the bed of the machine at I2.The operator, by manually engaging the lever 10, can move the rod 68"downward to thus move th carrier Ill downward in opposition to thespring 68. The carrier is thus separated from the wires and the fibersas shown in Fig. 7 to permit twisting. By moving the lever 70 upward thecarrier can be. restored. to its normal forward position, upward.movement. being effected by the spring. 66- A spring detent. 1.4. onthe. lever. JD

6 is engageable with depressions; "in a plate Hi, and the lever 10 andthe .parts controlled thereby can thus be retained in; theirlowerpositions or in their upper positions as. required.

Twisting mechanism The twisting mechanism does not of itself constituteany part of the present invention and it may be of any usual orpreferred form and. it may in factbe similar to the. twisting mechanismshown and. described in the before-men tioned Patent No. 2,358,443.

The twisting mechanism. comprises the beforementioned part I8 which is anonrotatable vise and which includes jaws for gripping. the wires A andC at one end.. The twisting mechanism also comprises a spindle l1carrying a'rotatable chuck 18 which includes jaws for gripping the wiresA and C at the other end.

The chuck 18 canbe rotated by means of belts l9 engaging a. pulley 89,.the saidbelts passing over. a drive pulley on an electric motor at therear which is not. shown but which is mounted on. the slide 20 andbodily movable therewith. The pulley is rotated continuously androtation can be transmitted to the chuck it! when required by means of afriction clutch at Bl. A hand wheel 82 is provided by means of, whichthe chuck can. be rotated manually to a limited extent for. a purpose tobe explained.

During twisting the twisting mechanism occupies a. position. at thefront of the machine but it is. not necessarily permanently located. inthis machine. Inv fact, the twisting mechanism is shown as carried. inits entiretyon the. slide as which also supports the carrier is and theparts directly associated therewith. Thus the carrier and the twistingmechanism move .rearwardly and forwardly in unison and are maintained infixed relationship with each other, except for the relative verticalmovements of the carrier which. have been described. When the twistingmechanism. is mounted on the slide 23 the driving motor for the dhuck l8is also mounted on the slide and moves with it.

The mechanism for controlling the jaws of the vise. l8 and of the chucki8 need not be described in detail and it is sufficient for purposes ofthe present invention tostate that the said jaws of the vise iii areoperated by a hand lever 83 and that the jaws of. the chuck H3 areoperated. by a hand lever 84.. The friction clutch for starting therotation of the chuck 18 is-operated by means or a foot treadle 8.5- atthe front of the machine where it can be readily reached by the foot of.the operator. By pressing on the foot treadle the. friction clutch. 81.can be engaged to start rotation of the chuck it and effect twisting.Either the vise [:8 or the chuck T8 or both of them. are longitudinallymovable on the slide 20 to take care of. the. shortening. of the brushas twisting takes place-.. Suitable means which need not be described indetail are provided for automatically disengaging the. friction clutchafter a predetermined amount of shortening of the brush, such shorteningbeing. dependent on the amount of twisting.

When the twisting, mechanism isbodily movable with the carrier, it is.necessary to. provide a suitable connection between the foot treadle andthe slide topermit such movement. As shown in Figs. 1 and.8,, the foottreadle Slioperates a. lever 86 secured to a transverse. rockshaft 81.Mounted. on the rockshaft .isa lever 75. 88: which is splinedl to the..shaf.t for. rotation therewith but which is movable longitudinallythereof. The lever 88 is held between two brackets depending from theslide 28 so as to be bodily movable with the slide. A member 89 is engaged by the lever 88 and this member serves to operate the clutch 8| bysuitable mechanism including a link 90. Thus the clutch is operable bythe foot treadle notwithstanding its bodily movements with the slide 20.

In order that the wires A and C may enter the vise I8 and the chuck 18when the positions shown in Figs. 2 and 4 are reached, the said vise andchuck are provided with vertical wire receiving slots, as shown in Fig.14. If the slot in the chuck I8 is not initially in its vertical Fibermagazine and operating mechanism therefor The fiber magazine and theoperating mechanism therefor do not of themselves constitute any part ofthe present invention and they may be similar to the magazine andoperating mechanism shown in the before-mentioned Patent No. 2,358,443.In describing the fiber magazine and the operating mechanism thereforreference will be had more particularly to Figs. 7, 8, 11, 12, 3, 18, 19and 20.

The fiber magazine I4 is carried by an elevated platform 94 supported onthe base of the machine by means of brackets 96 and 98. The magazine I4is essentially a rectangular container open at the top and at thebottom, and fibers are placed therein by the operator from time to timeso that a sufiicient supply is always maintained. One wall of themagazine, as for instance the left wall, may be movable to adjust thelength of the magazine for brushes of different lengths. Movable acrossthe bottom of the magazine I4 are two similarly formed, but oppositelypositioned, slicing bars I and I02. These bars are pointed at theirends, as shown in Fig. 18, and they are connected together forreciprocable movement in unison. Fig. 18 shows the carrier I0 inposition immediately below the magazine I4 for receiving a layer offibers therefrom. The bars I00 and I82 are shown as moving from left toright, and it will be seen that the fibers between the ends of the barsare free to move downwardly onto the carrier. As the bar I92 iswithdrawn it permits the fibers to move down-- wardly, and as the barI00 advances it slices off a layer of fibers, which layer remains on thecarrier I0. The bars support the fibers which are immediately abovethem, and when the slicing bar I 00 has moved entirely across the maga-18 shows the bars moving from left to right, and' when the carrier I0next reaches its fiber receiving position the bars will be moved fromright to left, slicing then being effected in the manner al readydescribed by the bar I02 instead of by the bar I00.

The two slicing bars I00 and I02 are carried by a slide I04 which ismovable horizontally in a guide rail I06 supported by brackets I08, I08depending from the platform 94. For supporting the slicing bars toprevent vertical vibration thereof two shelves I09, I 09 are'provided atopposite sides of the magazine I4. The said shelves are carried by theguide rail I06 and they are immediately beneath the bars. The slide I04is provided with rack teeth on its lower face which mesh with a gear II0, the guide rail I06 being cut away as shown in Fig. 20 to'permit thegear to engage the rack teeth. The gear H0 is carried by a shaft H2rotatable in bearings formed in brackets H4 and H6 depending from theplatform 94. Rotatably mounted on the shaft II2 are two bevel gears I I8and I20, these bevel gears meshing with a single bevel gear I22. Thebevel gear I22 is mounted on a shaft I24 supported in bearings inbrackets I26 and I28 depending from the platform 94. It'will be seenthat when the shaft I24 and the gear I22 are rotated the bevel gears IE8and I20 are rotated in opposite directions, which directions areindicated by arrows in Fig. 19. Connected with the respective bevelgears H8 and I20 are clutch members 30 and I32 which are adapted to beengaged by a single clutch member I34 rotatable with the shaft I I2 butlongitudinally movable thereon. By means of a yoke I36 and a lever I38the clutch member I34 may be moved in one direction or the other toengage either the clutch member I30 or the clutch member I32. Thus theshaft H2 and the gear IIO can be rotated in one direction or the otherto move the slide I04 and the slicing bars I00 and I02 in one directionor the other.

Mounted on the guide rail I06 for longitudinal movement is a rod I40,and this rod has a bushing I42 secured thereto, the said bushing beingpivotally connected with the lever I38. Secured to the rod I40 are lugsI44 and I46 which project forwardly and are adapted to ,be engaged bystops I48 and I 50 carried by the slide I04. The stops I48 and I50 areso positioned as to engage the respective lugs I44 and I46 at the propertimes in order to throw the clutch member 534 from one operativeposition to the other after the slide I04-and the slicing bars I00 andI02 have been moved sufiiciently in one direction or the other. As shownin Figs. 19 and 20, the slide I 04 and also the slicing bars and thestop I50 have been moved toward the left so that the stop is inengagement with the lug I46, and the stop has moved the said lug and therod I40 sufficiently to throw the clutch member I34 out of engagementwith the clutch member I32 and. into engagement with the clutch memberI30. During the next following cycle, the slide I 04 and the slicingbars will be moved toward the right until the stop I48 engages the lugI44, thus moving the rod I40 to throw the clutch member I34 out ofengagement with the clutch member E30 and into engagement with theclutch member I32. Suitable means, such as an over-center spring I52, isprovided to insure movement of the clutch member I34 sufiiciently tofully engage the respective clutch members I30 and I32.

Mounted on the shaft I24 is a drive pulley I54 which is rotated by abelt I56 passing over a pulley I58, projecting from a reductiongear'unit I60 connected with a motor I 62. Connected with the pulley I54is a clutch I64 which, when e'ngaged. causes the shaft I24 to rotatethrough a single revolution in the direction .indicated in Fig. 19. Theclutch I64 has a notch providing an abutment adapted to be engaged by apawl I66 (Figs. 12 and 13), and this ipawl,'wh'en engaged, preventsrotation of the shaft. The pawl I66 is mounted on a shaft I68 (Figs. 12,13 and 19) and a spring I10 biases the pawl toward its engagingposition. At the right end of the :shaft I68 is a toothed member I12which :has a lost motion relationship with the shaft, being normallyheld by a spring I13 in the relative position shown in Fig. 12.Positioned below and parallel with the shaft I68 is a rockshaft I14carrying at its right end a toothed member I16 adapted to engage thetoothed member I12. .At the left end of the shaft I14 is a lever I18(Figs. 13 and 20) carrying a projecting pin I80. A spring I 82 biasesthe shaft I14 so that the pin I80 is normally held in its forwardposition, .as limited by a stop pin 184. With the parts in the positionsdescribed the tooth on the member I16 is in front of the tooth on themember I12 as shownin Figs. 8, 11 and 12.

Carried by the bracket 22 on the slide 201is a member I86 which is sopositioned that it engages the pin I80 as the slide 20 reaches itsrearward position with the carrier I0 immediately below the magazine I4.The pin I80 is moved rearward thus turning the rockshaft I14 in thecounterclockwise direction as viewed .in Fig. 13, or in the clockwisedirection as viewed in Fig. 12. The rockshaft I14, moving in theclockwise direction as viewed in Fig. 12, moves the toothed member I16in the same direction, thus causing the tooth thereon to engage 'thetooth on the toothed member I12 and moving the rockshaft I68 and thepawl I66 in the counterclockwise direction to disengage the pawl fromthe one-revolution clutch I'64. This starts the rotation of the shaftI24 in the clockwise direction thus moving the slicing bars I00 and I02in one direction :or the other by means of themecham'sm which hasalready been described.

As soon as the teeth on the members I16 and I 12 have become disengaged,the :pawl is free to move rearwardly under the influence of the spring110, and is ready to engage the notch in the clutch at the completion ofa single revolution, thus stopping further rotation of the shaft I24 andof the parts connected therewith. After the fibers have been distributedon the carrier II! by means of one or the other of the slicing bars, theslide 20 and the parts carried thereby, including the member I86, aremoved in the forward direction, and the rockshaft I14 is moved by thespring I82 so that the said shaft and the parts carried thereby,including the toothed member I1-6, are restored to the positions shownin Figs. 12 and 13. The tooth on the member I16, in moving forward, mustpass-by the tooth on the member I12. This is made possible by the before-mentioned lost motion connection of themember I12 with the shaft I68.The member I12 is rotated in the clockwise direction, as viewed in Fig.12, in opposition to the spring I13 sufficiently to permit the tooth onthe member I16 to pass. Then the member I12 is restored by the spring tothe position shown in Fi 12.

v Wire feeding means In describing the wire feeding means reference 10will be had more particularly to Figs. '1, 8, 9,- 10, 15, 16 and 17.

Depending from the platform 94 are two brackets I88 and IE0, and thesebrackets carry a horizontal plate I92. Supported on the plate I92 aretwo pairs of blocks I94 and I86. The two pairs of blocks are spacedapart longitudinally as shown in Figs. 7 and 15. Carried by the frontblocks I94, I64 is an inclined plate I98 which serves as one wall of awire magazine 2B0. The blocks of each pair'are spaced apart as shown inFig. 17 to provide a vertical wire channel 202 communicating with themagazine 290. Mounted in apertures in the blocks I96, I96 is a rotatbleshaft 2E4 which carries a longitudinal serrated roller 205, the lengthof which is only 'a little less than the total distance between theblocks. At the left end of the shaft 204 is a manually operable knob208.

Carried by studs projecting toward the right from the right hand blocksI94, I96 is a vertical plate 2H3, the upper end of "which is flaredtoward the right. Carried by studs projecting toward the left from theleft hand blocks I94, I96 is a vertical plate 2I2, the upper end ofwhich is flared toward the left. The spacing between the plates 210 and2I2 is substantially equal to the length of the wires that are to beused, and these plates serve to hold the wires in proper positions andto prevent them from being displaced longitudinally. If the length 'ofthe wires is to be changed the plate 212 can be-moved toward the rightor toward the left by replacing the studs which carry itand bysubstituting longer or shorter studs.

In use a supply of wires cutto suitable length is placed in the magazine200, the wires being located as to their longitudinal positions by theplates 2H! and 2.!2. The wires tend to move by gravity into the channel202 which is ordinarily completely filled. The roller 206 serves as anagitator for the wires and if the wires fail to move freely by gravityinto the channel 202, the roller can be turned by means of the knob 208to agitate the wires and facilitate their entry into the channel 202.

Mounted in bearing brackets 214 and '2I6 below the plate I92 is.a..ro.ckshaft 2I8. Secured to the rockshaft are two segments 220 and222 which are immediately beneath the .lower :end of the wire channel.282, each segment having .a wire receiving notch 224 therein, as shownin Fig. 17. When the segments are in their normal positions, as shown inFig. 8, the notch 2.24 of each segment is immediately beneath the wirechannel 202 so as to receive one wire therefrom. When the segments arerotated through approximately in the counterclockwise direction to theposition shown in Fig. .17, the wire entered in. the two notches ismoved to the position shown in Fig. 1'1, and the wire can then drop ontothe carrier II] when the said carrier is either in the position shown inFig. 2 or the position shown in Fig. 4. The shaft i2l8 tis-anormallypositioned to hold the notches 2.24 in register with the wire channel202 by means of a spring 226 which engages a pin 0131.311 arm 228secured to the shaft.

Secured to the shaft 2 I 8 at the right end thereof is a cam member 230.This cam member has a tooth 232 which extends in a generally downwarddirection when the cam member is in :its normal position as shown inFig. .8. The cam member also carries a pm 234 which projects toward theright. A

Suitably secured in fixed position on the slide 29 is a cam member 236,this cam member being so positioned that it can engage the pin 234 whenthe slide is moved. Pivotally mounted on the cam member 236 is a secondcam member 238 which is positioned to engage with the tooth 232 of thecam member 230 when the slide is moved. The cam member 238 is biased bya spring 248 and is normally held in the relative position shown in Fig.9.

When the slide 20 and the parts carried thereby move rearward the cammember 238 engages the tooth 232 and moves the said tooth from theposition shown in Fig. 8 to the position shown in Fig. 9. Thus the shaft2I8 and the parts carried thereby are rocked in the counterclockwisedirection from the positions shown in Fig. 8 to the position shown inFigs. 9, 16 and 17, and a single wire is released from the notches 224in the segments 22!], 222. This wire falls onto the carrier II] which isthen in the position shown in Fig. 2. As soon as the cam member 238passes beyond the position shown in Fig. 9, the shaft 2I8 and the partscarried thereby are restored to their normal positions by the spring226. It will be seen, by reference to Fig. 9, that the pin 234 has beenmoved to a position such that it i not engaged by the cam member 236 asthe said cam member moves rearward.

When the slide 20 and the parts carried thereby are returned in theforward direction, the cam member 236 engages the pin 234 to again rockthe shaft H8 and the parts carried thereby in the counterclockwisedirection from the positions shown in Fig. 8 to the positions shown inFigs. 1-0, 16 and 19. Again a single wire is released from the notches224 in the segments 22B, 222. This wire falls onto the carrier In whichis then in the position shown in Fig. 4. As the parts move in theforward direction the cam member 238 may reengage the tooth 232 as shownin Fig. 10. Such engagement causes the cam member 238 to turn in theclockwise direction in opposition to the spring 240, and it is thus ableto pass by the tooth 232. After passing the said tooth 232 the cammember 238 is returned to its normal position by the spring 240.

Operation During operation of the machine the operator maintains asupply of fibers in the fiber magazine I4, placing additional fiberstherein as the supply is depleted. The operator also maintain a supplyof wires in the wire magazine 200, rotating the agitating roller. 206from time to time as may be necessary to keep the wire channel 202filled.

With the slide 20 in its forward position the operator turns the chuckI8 by means of the hand wheel 82 to whatever extent may be necessary tobring the slot therein in vertical position as shown in Fig. 14. Thenthe operator, by means of the handle 50 and the valve unit 48, causesthe slide and the various parts carried thereby to move to the rearwardposition and then back to the forward position. As the slide movesrearwardly one wire from the wire feeding means I6 is deposited on thecarrier in the manner already described, the ends of this wire passinginto the vertical slots in the vise I8 and in the chuck I8. When theslide reaches its rearward position the carrier I has been moved upwardso that it is immediately beneath the magazine I4 as shown in Fig. 18,and the member I86 engages the pin I80 to release the one-revolutionclutch I64 thus starting the movement of the slicing bars I00 and I02.If the slicing bars are in their left hand positions, as shown in Figs.1, 19 and 20, the gear wheel I I0 is rotated in the clockwise directionto move the bars from left to right, thus slicing off a layer of fibersfrom the supply in the magazine I4, as clearly illustrated in Fig. 18.Inasmuch as one wire has been previously deposited on the carrier II!the layer of fibers i above the said wire. When the slicing bars havecompleted their movement, the stop I48 engages the lug I44 to throw theclutch member I34 from the position shown in Fig. 19 to its oppositeposition. At or about the time the clutch is shifted, the shaft I24 hascompleted its single revolution and the slicing bars remain in theirright hand positions ready for the next cycle.

As the slide 20 and the parts carried thereby move forwardly a secondwire is deposited from the wire feeding means It onto the carrier, thissecond wire falling on top of the fibers which are thus positionedbetween the two wires. The ends of the second wire also enter thevertical slots in the vise I8 and in the chuck I8.

After the slide and the parts carried thereby have reached the forwardposition, the operator can then inspect the fibers to make sure thatthey are uniformly distributed and otherwise in proper condition fortwisting. For some brushes it is found desirable to remove a few fibersfrom each end of the layer to insure more satisfactory twisting. Afterthe operator has inspected the fibers and has made any necessary changesin the distribution thereof, the jaws of the vise I8 and of the chuck 18can be engaged with the wires by means of the levers 83 and 84. By meansof the lever Ill the carrier I0 is lowered by the operator to theposition shown in Fig. 7 so that the carrier will not interfere in anyway with the twisting operation. The next step is for the operator tostart the twisting by depressing the foot treadle 85 so as to engage theclutch 8|. After the brush has been fully twisted, as shown in Fig. 7,the twisting is stopped and the jaws of the vise and the chuck may betemporarily disengaged from the wires and the vise and chuck may beseparated and again reengaged with the wires. After that a supplementaltwisting of the ends of the wires may be effected to twist the endportions thereof in such a manner that they are in condition to besubsequently engaged by the handle in which the brush is to be mounted.

After the twisting of the brush has been completed and the twisted brushhas been removed, the carrier II] is moved upward by the lever I0 andthe machine is ready for the making of the next following brush. Inmaking such next following brush the procedure is exactly the same asthat already described except that the slicing bars move from right toleft instead of from left to right.
